LED advantages

control spectral composition, the ability to produce very high light levels with low radiant heat output when cooled properly, and the ability to maintain useful light output for years without replacement.

LEDs are safer to operate than current lamps because they do not have glass envelopes or high touch temperatures, and they do not contain mercury.

The spectral output of an LED lighting system can be matched to plant photoreceptors and optimized to provide maximum production without wasting energy on nonproductive wavelengths (Dougher and Bugbee, 2001; Sager et al., 1982). The ability to dynamically control the spectral output can also be used to influence plant morphology (Heo et al., 2002). Spectra can be customized for specific crops or production protocols and the output even modified over the course of a photoperiod or growth cycle. Special lighting modes might possibly even be used to enhance disease or injury visualization (Schuerger and Richards, 2006).

LEDs turn on instantly and do not require warmup time. They also turn off instantly. Because they are solid-state devices, LEDs are easily integrated into digital control systems. This allows complex control options not generally available with other light sources. LEDs can be continuously dimmed between zero and maximum, and custom spectra (Fujiwara and Sawada, 2006) and custom programs such as sunrise and sunset simulations can be programmed. When used in arrays, LEDs can be configured for control by zone, ensuring only areas containing plants are illuminated. More advanced capabilities include the ability to integrate sensors that can dynamically control light level based on inputs such as available solar lighting or the proximity of plants.

LEDs have the potential for significant cost savings over current horticultural lamp types. Because of their long operational life, procurement and disposal costs for replacement bulbs is mostly eliminated along with associated labor costs. There are no ballasts to be replaced either.

Taking into account lamp ballasts and drivers, preliminary calculations indicate that the LED array provides three times more light output for the same watt of input power on an equivalent area basis.

each decade, LED prices have fallen by a factor of 10 while performance has grown by a factor of 20. This phenomenon is known as Haitz' Law.

conomy of scale will drive significant cost decreases.

Devices in the ultraviolet wavebands, however, still have low output. Ultraviolet A wavelengths (320 to 400 nm) are of particular interest because they can play a role in preventing a physiological disorder termed intumescence injury (Morrow and Tibbitts, 1988) that impacts a variety of plants grown in protected environments. Also, ultraviolet B radiation (290 to 320 nm) may be useful in manipulating phenolic phytonutrients to improve dietary value in greenhouse or controlled environment-grown crops like lettuce

Amazing:

Over time, as new LED chip technologies became available, LED modules using very high density chip-on-board technology were developed. One such module (Fig. 1), often referred to as a “light engine,” was 1 inch2 (6.5 cm2) in area and contained 132 LEDs in five colors (Emmerich et al., 2004). This technology is too expensive for large-scale use, but is ideal for specialty or research applications that require high light output at several independently controllable spectral bands. pic: http://hortsci.ashspublications.org/content/43/7/1947/F1.expansion.html

Customer Testimonials

Speedy and Professional!

LEDs Grow Lights Depot was amazingly helpful with speedy, professional email replies to my many questions. I had an exceedingly wonderful experience doing business with them. They truly treated me like a best friend. The website is easy to navigate and they have wonderful promotions and great prices! The bar LEDs I purchased of similar wattages put out more light and less heat than t5 high output lamps which is wonderful for my orchids. I was always battling heat and low humidity. When I need more lights, I will definitely purchase them from this company again, and I will recommend them to anyone interested in LED lighting!" - Anna

Great customer service!

I appreciate your great customer service. It has to be the fastest, friendliest response I've ever gotten from a company. Ill be recommending your company to everyone I know. Thanks again. - Cody

Fast shipping and excellent customer service!

The shipping was fast and the customer service is excellent . I would definitely buy again in your store. - Adriana

Great growth and helpful service!

Very happy with the product to date. Is an excellent little unit thats delivering great growth and cool living environment.
Big thank you to Erik and the team at [LED Grow Lights Depot] for their fast helpful service. - Ricky

Very pleased with the customer service and performance!

The fixture arrived even faster than expected and in perfect condition. I was very pleased with the customer service and performance of LED Grow Lights Depot and will use them again for future orders. - Emily

Major results!

Major results in just 1 week, it's like the foliage doubles every 24 hours. We ended up buying another one! -Terri

Excellent product and service!

Excellent product and service, sweet light, plants love it. - Eric

Kind LEDs are great!

The Kind LEDs are great! I've been growing with LEDs for many years and after purchasing my first two xl1000's I must say I'm very pleased. They are by far the most efficient lights I've used(and I've tried many). I eagerly await the light bars I feel they would be wonderful lights to use supplementary. Can't wait to try all the new toys Kind will be blessing us with in the years to come. Simply put, they produce great products. -Ted

Great customer service!

Your customer service has been great, I would buy from you again without hesitation. -Dan

I will be back!

I had originally ordered the dwarf star, but it turned out they had ran out of stock before filling my order, so instead of making me wait, they upgraded my light for the inconvenience!! This is an amazing company and the ps500 exceeded my expectations. Erik was awesome and very helpful. Will definitely be back! -Carson
